Setting up Multicasting

English Network/Internet
1

At work we’re trying to setup a Tumbleweed machine that will only route multicasting between 3 networks. The 3 cards are set with static IPs. The routing table is setup with the 1st interface having the gateway address on it. 224.0.0.0 is assigned to each of the interfaces. From the outside, we can ping the primary interface but not any of the other 2.

route -n

In searching the web, I see references to a mulitcast daemon, but I do not find it in the system.

What do I need to do to get this working?

What kind of multicasting are you routing?
Shouldn’t you be assigning your interfaces multicast addresses?

TSU

Do you have static list of predefined multicast groups or do you need to support dynamic registration of arbitrary multicast groups?
